ICCUP: A/B Tour Series

Cross Game is a two player map made by CrystalDrag from the map making community at broodwarmaps.net. It is one of six maps that were used in the BWMN Open
Notable Features

Loosely based on the SC2 map Daybreak
Doodad Overlord Spot — The naturals have an Overlord spot made of doodads mimicking the effect of a high ground cliff (due to the lack of available high ground terrain on Ash world tileset)
Cliffable corner expansions: There are low ground cliffs for drops behind the corner expansions.
Vision blockers: The row of bushes, next to the mineral only expansion, blocks vision for ground units, similar to SC2.

Mist was introduced in the 9th SonicTV Starleague.
Notable Features

Easy harassment of the mineral lines of all expansions, including the naturals, similar to previous Earthattack maps such as Outsider or El Niño/Great Barrier Reef. Not only the terrain right behind the natural is not buildable, but it can be accessed through a back door, contrary to most maps where it is simply a cliff or another non walkable terrain.
The bridge in the centre of the map is entirely made up of vision blocking tiles, limiting the vision range of any ground units on the bridge to the bare minimum.
The geyser of the expansion counterclockwise from each player can be attacked from ranged units in the opponent's main whereas it is much easier to access by ground from the other player, which makes it very hard for any player to ever get control over that expansion.

Overwatch is a map that was used in the foreign BroodWar scene made by -NegativeZero-. It first appeared in the SBWI Summer Tour of 2013 and was later used for the first SBWI Teamleague.
Notable Features

tight rush path — the direct rushing and scouting path bewteen both players is constricted by bridges and a tight gap in the centre of the map, giving players tactical opportunity to intercept an incoming enemy and forcing bigger armies to take wider alternative routes around the map
high ground pods — There are two big high ground pods along the main path from the natural to the centre of the map, which are important for players to control to gain a tactical advantage in engaging the third gas expansion
curved ridges — the centre of the map is dominated by two curved ridges that offer positional advantage to the player gaining position on them in an engagement.

Avalon (아발론) was released in December 2014 to be introduced in the HungryApp Starz League with Kongdoo, alongside the map Demian.

Although Avalon's configuration of bases and wide use of ramps does not quite resemble any of the commonly played maps, its four starting positions in the four corners surrounded by expansion sites with a large flat center area will be familiar to most players.

Notable features include a perimeter of interconnected expansion sites, only separated by a series of the Xel'Naga Temples (5000 HP), including a mineral-only third located behind the main base. These temples are reminiscent of those in Neo Electric Circuit, a commonly-played map in the current era, where temples also serve to impeded movement through a ramp of a potential expansion site. Even without destroying the temples, these nested expansion sites are sufficiently vulnerable to attack as they are quite open to the center battleground, with only a ramp choke point slowing down opponents and reinforcements.

The expansion sites located behind each main base is reminiscent of maps such as Gorky Island, where these expansion are somewhat secluded from land attack, but readily open to air and drop attacks. Furthermore, reinforcements will likely be delayed as unit rally points will likely be near the natural expansion, which is located relatively far from this mineral only expansion. Notably, the presence of such bases behind the main causes these main bases to feature substantial space behind the mineral lines which, while enable air attack or drop harass, also provide much land for anti-air defense structures.

Interestingly, the map features a large number of ramps, thus constricting ground troops in many instances (although it should be noted that ice terrain, making up the centre and part of the side paths of the map, is considered by BW to have the same low ground elvation as the surrounding dirt/snow terrain ; therefore ice ramps lack the vision and hit chance impairing characteristics normally associated with ramps).
